Two best friends, Ben Affleck and Matt Damon, sit down to write their first screenplay, an adaptation of “Catcher in the Rye” (obviously) when suddenly a fully realized script falls from the sky. The name on that script: “Good Will Hunting”. What will these two friends do? Can fame literally land in your lap? Written by Mindy Kaling (of NBC’s “The Office”) and Brenda Withers, this gender-bending Off-Broadway hit is a sharp skewering of celebrity culture and an affectionate look at one of Hollywood’s favorite bromances. Bring a friend. Some things are meant to be shared.
